If a flagger is directing traffic in a construction zone, you must:

Be prepared to reduce your speed and use caution when directed to do so by a sign, flagger, or law enforcement officer. Failure to do so is illegal and is dangerous to those working in construction zones.

• Follow the directions given by the flagger.
• Copy what surrounding traffic is doing, despite the flagger's instructions.
• Assume the flagger is not supposed to be directing traffic.
• Follow the laws that would be in place if the area was not under construction.
